No, you do not. All you need to make sure to attach to your return is the Schedule W that was printed with your return. It lists all of your 1099, W2, etc. information. Keep those forms for yourself.
I have also included a link to the instructions at the bottom of this page.
If you are claiming a refund, mail your return to:
Rhode Island Division of Taxation
One Capitol Hill
Providence, RI 02908 – 5806
If you are making a payment, mail your return to:
Rhode Island Division of Taxation
One Capitol Hill
Providence, RI 02908 – 5807
